Digital broadcasting system and method of processing data in digital broadcasting system
First Claim
1. A method of processing data for a receiver, the method comprising:
- receiving and demodulating a broadcast signal comprising a fast information channel (FIC) including cross layer information for mobile service acquisition, a transport parameter channel (TPC) including FIC version information for identifying an update of the FIC, and mobile service data belonging to a desired ensemble, wherein the mobile service data is data encoded through a Reed-Solomon (RS) frame;
acquiring a first ensemble identifier identifying the desired ensemble from the FIC;
obtaining a service map table (SMT) from the desired ensemble, the SMT comprising a header and a payload, the header including a second ensemble identifier corresponding to the first ensemble identifier, the payload including service acquisition information of the desired ensemble;
acquiring IP access information of a mobile service from the SMT and acquiring IP datagram of the mobile service data from the ensemble according to the acquired IP access information; and
decoding at least one of audio and video streams included in the acquired IP datagram of the mobile service data.

Abstract
The present invention provides a data processing method. The data processing method includes receiving a broadcast signal in which main service data and mobile service data are multiplexed, acquiring transmission-parameter-channel signaling information including transmission parameter information of the mobile service data, and fast-information-channel signaling information, acquiring binding information describing a relationship between at least one ensemble transferring the mobile service data and a first virtual channel contained in any of the at least one ensemble by decoding fast-information-channel signaling information, acquiring ensemble identification information transferring the first virtual channel using the binding information, and receiving at least one mobile service data group transferring an ensemble according to the ensemble identification information, parsing service table information contained in the ensemble and decoding content data contained in the first virtual channel using the parsed service table information, and displaying the decoded content data.
